Description
Technical field
This utility model relates to a kind of actuating device, particularly to a kind of middle straight gear, belongs to plant equipment manufacture and adds
Work technical field.
Background technology
Gear is the mechanical organ having tooth can engage transmitting movement and power continuously on wheel rim, plays biography in plant equipment
Action is used.Middle straight gear is of paramount importance machine components in actuating device, it is necessary to assure reliability of gears is good, transmission
Stable, service life is long, but existing gear function is the most single, weares and teares more serious, use the longevity after working long hours
Order short, it is necessary to design one adds the convenient gear of lubricating oil, it is to avoid abrasion, extends service life of gear.
Utility model content
This utility model purpose is the middle straight proposing length in a kind of service life in order to overcome the deficiencies in the prior art
Gear.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of middle straight gear, including gear originally
Body；The center of described gear axially has axis hole；Described gear is two grades of stair-stepping cylinders, and its diameter is big
One end be first step portion, one end that diameter is little is second step portion；It is toothed around on the excircle in described second step portion；
Described take turns that tooth width is second step width 2/3rds；An annular is formed recessed between the described gear teeth and first step portion
Groove；Described first step portion offers an annular oil groove away from the side portion of the gear teeth；Offer many in described first step portion
Individual oilhole；Annular oil groove is connected by described oilhole with annular groove.
Preferably, the end of the described gear teeth is provided with 45 ° of chamferings.
Preferably, described oilhole has 4 or 6, and is uniformly distributed.
Due to the utilization of technique scheme, this utility model compared with prior art has the advantage that
Middle straight gear structure of the present utility model is simple, reasonable in design, adds lubricating oil before installing in annular oil groove,
Then sealing with the annular silica gel strip coordinated, when gear uses, the lubricating oil in annular oil groove enters the gear teeth by several oilholes,
Effectively lubricating during gear teeth motion, is prevented effectively from abrasion, extends service life of gear.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings technical solutions of the utility model are described further:
Accompanying drawing 1 is structural representation of the present utility model.
In figure: 1, gear；2, axis hole；3, first step portion；4, second step portion；5, the gear teeth；6, annular groove；7、
Annular oil groove；8, oilhole.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
A kind of middle straight gear of the present utility model, including gear；The center of described gear 1 axially has
Axis hole 2；Described gear 2 is in two grades of stair-stepping cylinders, and one end that its diameter is big is first step portion 3, and diameter is little
One end is second step portion 4；It is toothed around 5 on the excircle of described second step 4；The described gear teeth 5 width is second step portion 4
2/3rds of width；An annular groove 6 is formed between the described gear teeth 5 and first step portion 3；Described first step portion 3 is remote
An annular oil groove 7 is offered from the side portion of the gear teeth 5；Multiple oilhole 8 is offered in described first step portion 3；Described oilhole 8
Annular oil groove 7 is connected with annular groove 6.
Further instruction, the end of the described gear teeth is provided with 45 ° of chamferings, convenient during in order to install, and prevents the gear teeth that wear and tear.
Further instruction, described oilhole has 4 or 6, and is uniformly distributed.
Middle straight gear structure of the present utility model is simple, reasonable in design, adds lubricating oil before installing in annular oil groove,
Then sealing with the annular silica gel strip coordinated, when gear uses, the lubricating oil in annular oil groove is slowly entered by several oilholes
The gear teeth, effectively lubricating during gear teeth motion, it is prevented effectively from abrasion, extends service life of gear.
Below it is only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limit
System.All employing equivalents or equivalence are replaced and the technical scheme that formed, all fall within this utility model rights protection scope it
In.
